Thanks! I did use a carbide tipped blade but I very much doubt it was a quality one, just a cheesy one that came on the saw. A higher quality carbide blade would likely do wonders for cutting thin sheet metal like this 👍

@dannybojat carbide blade flipped backwards 🤔

Chris Campbell Excellent! Thanks for watching!

Awesome! 👍

Great! Did you try this out?

yes i did. wasn't an exact replica of yours but same basic design. my son fed soffit through, i measured and stopped it and made cut. made job go quickly ! Thanks for great tip!!!

Gussy Holm Excellent, glad to hear that!

That’s wonderful! Thank you for dropping by!

Absolutely, you could add a 45 insert to do mitres too.

Could you use a sliding chop saw for this?

I don't see why not. I think this is more for if you don't have one though.

Thanks! Project is DONE! Used my sliding miter saw with the blade turned around.

+brimest0ne That's awesome!

That’s an excellent idea

You got it 👍

Yup, the fascia goes on before the gutters go up and yes the top edge of the fascia tucks in behind the drip edge. Hopefully you already have drip edge installed on your roof because it gets nailed down under the last row of shingles. The gutter typically gets installed under the drip edge too.

That might work, but keep in mind that reversing the blade means the backside of each tooth is striking the workpiece, not the front. This is especially helpful with sheetmetal because the teeth are too aggressive for such thin material, the backside of each tooth cuts less material and results in a better cut. You could try your method, but ultimately turning the blade around takes a minute and you can switch it back once all of the soffit has been cut, not a big deal.

Yup exactly

You can adjust the height of the blade to only cut so deep. In this case i adjusted the blade to only just graze the plywood below.

@@PatonHaus thank you very much I just now set it up and it works great 😁😁😁

I just used the blade that came on my saw, the aluminum is very thin and soft so I imagine most blades will cut just fine. You can experiment with reversing the blade if it doesn’t cut right the first time.

@Kyle Oneill do it that way for aluminum? Thank you very much 😊

Thank you very much for all the help I just set it up and it works great. 😁

I tried cutting without reversing the blade and it absolutely obliterated the soffit. Turning the blade around resulted in a very clean cut. I’m sure there are different ways to get a good result, this is what worked for me.

Now days they make purpose build blades for cutting sheet metal. Much better and safer option IMO.

Jerry Peckford Hi Jerry, for whatever reason with the blade in it's normal orientation it just shreds the aluminum to bits. Turning the blade around makes a MUCH cleaner cut.

+PatonHaus now that it's a year after your reply, do you have any new information about why the saw blade was making a mess unless it was turned backwards? Did you just happen to figure out this trick yourself or did you learn about it somewhere else?

I don't know who started the blade backwards thing, but you put a plywood blade in the proper way and pull the saw backwards through the material. It then cuts down pushing the material into the table instead of pulling the soffet up.

That could be due to two things, one of which is your blade and whether it is in good shape. The second thing is whether the soffit is allowed to slap up and down during the cut. Try holding your soffit down using another piece of wood to prevent it from slapping up/down, and make sure you have a nice sharp blade.
